Subsequently, a check is made by the manufacturer and the preconfigured angle sensor is then delivered to a customer. This takes from another manufacturer a housing cover blank made of plastic, which is usually produced by injection molding, and manufactures the angle sensor angle sensor module in that initially the preconfigured angle sensor is electrically connected to a so-called lead frame by welding or soldering. Subsequently, the leadframe is inserted into the housing blank and the leadframe is overmolded with a thermoplastic, wherein a separate cover must protect the sensor, otherwise it would be damaged. Finally, a function check of the finished housing cover must be made again.
